A relational database organizes data into tables, where rows signify records and columns denote attributes. Tables are linked via keys, enhancing efficiency in data management and querying.
- Key-value pair storage (A) is typical of NoSQL databases like key-value stores.
- Hierarchical structure storage (C) characterizes hierarchical databases, which employ a tree-like organization.
- Graph data storage (D) pertains to graph databases, representing data as nodes and edges.
Consequently, the correct option is (B): relational databases utilize tables for data storage.
